Business

Equillium, Inc. is a biotechnology company developing novel therapies for severe autoimmune and inflammatory disorders. The company's primary pipeline includes EQ504, an aryl hydrocarbon receptor modulator in preclinical development for ulcerative colitis and gastrointestinal diseases, and EQ302, a selective inhibitor of IL-15 and IL-21 in preclinical development for celiac disease and inflammatory bowel disease. Equillium acquired these programs through the acquisitions of Ariagen, Inc. in October 2024 and Bioniz Therapeutics, Inc. in February 2022, and does not operate manufacturing facilities, relying instead on contract manufacturing organizations for all drug substance and product needs.
